user account shows no networks in available wireless networks

hi, i have the following problem:

i do have 80 identical tabelt pcs (win xp tablet ed. 2005). all are capable
of wifi and are cloned (via sysprep) from the same master.

one user (limited user account) has the problem that he does not see any
networks in the available wireless networks window.

the local administrator on the same machine does see all available networks.

the other 79 users (limited user account) do not have any problems with
wireless networking.

the machines and users are all effected by the same gpo's (which do not
interfere with wireless networking).

i am using a intel/pro wireless 2200bg with the build in windows connection
software.

does anyone know what the problem could be or has some hints to resolve the
problem?

bye martin
